Investment Rating - The report maintains a Neutral rating for HUTCHMED (HCM) with a 12-month price target of $18 for the ADR listed in the US, indicating a potential upside of 32.4% from the current price of $13.60 [12][14]. Core Insights - Increased investor focus is expected on savolitinib following data presentations at ASCO, with the company highlighting severe under-detection of MET amplification when using NGS testing compared to FISH testing [1][2]. - The company’s internal unpublished data suggests that only about 30% of patients who test positive for MET amplification via FISH would also test positive using the NGS method [2]. - The global Phase 3 SAFRON study of savolitinib in combination with osimertinib will offer patients the option of two companion diagnostics: FISH and IHC methods [2]. Summary by Sections MET Amplification Testing - Testing for MET amplification is crucial for patient selection, with a cross-study analysis indicating that NGS testing severely under-detects the biomarker compared to FISH [2]. - The MARIPOSA-2 study detected MET amplification in 14% of patients using ctDNA NGS, while the SACHI study showed approximately 30% detection using tissue FISH [5]. Clinical Efficacy - The SACHI study demonstrated a median progression-free survival (PFS) of 8.2 months for the savolitinib plus osimertinib combination compared to 4.5 months for chemotherapy, with a statistically significant hazard ratio of 0.34 [5][6]. - For patients previously treated with a 3rd-generation EGFR TKI, the median PFS was 6.9 months for the combination arm versus 3.0 months for chemotherapy, also showing a significant difference [6]. Safety Profile - The SAVANNAH study indicated a promising PFS curve separation with a manageable safety profile, although adverse events leading to dose interruption of savolitinib occurred in approximately 48% of patients [9].
